State on path 16.In addition, the medium M in the printing equipment 1 of the present embodiment is placed on transport path 16 by Fig. 4 expressions
State, and be the stereogram from being carried out from the direction different from Fig. 3, and indicate the state being exaggerated compared with Fig. 3.
On the other hand, Figure 14 is figure corresponding with Fig. 2, and is the ejection model of the supporting part 117 of the printing equipment of reference example
The stereogram around 115 is enclosed, and indicates the state not being placed in medium M on transport path 116.In addition, Figure 15 is and Fig. 3 pairs
The figure answered, and be the solid around the ejection range 115 of the supporting part 117 of the major part of the printing equipment as reference example
Figure, and indicate state medium M being placed on transport path 116.In addition, Figure 16 is figure corresponding with Fig. 4, and indicate joining
Medium M is placed in the state on transport path 116 in printing equipment as usual, and to be seen from the direction different from Figure 15
The stereogram examined, and indicate the state being exaggerated compared with Figure 15.
As shown in Figure 14, the printing equipment of reference example has on the position for spraying range 115 is used as bearing surface 103
The first bearing surface 103a, the second bearing surface 103b and third bearing surface 103c.First bearing surface 103a is in width direction
It is arranged with the mode of multiple recess portions 125 (recess portion 125a) on B and is formed.In addition, the second bearing surface 103b is in the first bearing
The downstream side of the conveying direction A of face 103a in the mode of multiple recess portions 125 (recess portion 125b) is arranged on width direction B and by shape
At.Also, third bearing surface 103c is, the downstream on the conveying direction A of the second bearing surface 103b is laterally far from blowing unit
Direction bending bending section.
In this way, when being in that arrangement form there are multiple recess portion 125a on width direction B in the position for spraying range 115, deposit
In following situation, that is, medium M is concave corresponding to recess portion 125a, and can spray ink on concave medium M, to corresponding
Make the landing position offset of ink in the concave of medium M, so that image quality reduces.Moreover, the printing such as reference example fills
It sets like that, when recess portion 125a has periodically been arranged to form multiple on width direction B, the landing position of ink may
Periodically deviate on width direction B, thus will produce periodic image quality reduces.
Moreover, the downstream side on the conveying direction A of recess portion 125a and recess portion 125b is closed.In other words, bearing surface
Recess portion 125 is not formed in the end in the downstream side of 103 conveying direction A, but as the protrusion between recess portion 125
(flank) mutually level face.Therefore, even if for example making medium M swellings etc. to medium M due to medium M ejection ink
Occur in the case of tilting, the tilting effectively downstream side loss on conveying direction A that can make medium M will not be become
Structure.Therefore, as shown in Figure 15 and Figure 16, fold (linear heaves) L is easy tod produce, and fold L is easy to
Growth, and fold L is highly susceptible to get higher.When the height of fold L is got higher, fold L and blowing unit may interfere.
Moreover, in the present specification, " height " refers to, the position on direction intersected with bearing surface, and it is not limited to lead
The upward position of histogram.
On the other hand, as shown in Figure 2, the printing equipment 1 of the present embodiment has on the position for spraying range 15
The first concave-convex bearing surface 3a is not formed on width direction B, using as bearing surface 3.It is assumed that the first bearing surface 3a be in
In the case of forming irregular bearing surface on width direction B, medium M can deform along the bumps of bearing surface.Pass through
First bearing surface 3a is set as concave-convex shape is not formed on width direction B, be become to the printing equipment 1 of the present embodiment
It can be to the knot that is inhibited of the case where medium M deforms along the first bearing surface 3a on the position for spraying range 15
Structure.
In addition, as shown in Figure 2, the printing equipment 1 of the present embodiment is on the conveying direction A of the first bearing surface 3a
There is the arrangement form on width direction B to have the second bearing surface 3b of multiple recess portions 25 in downstream side, using as bearing surface 3.This
To locate, the downstream side on the conveying direction A of recess portion 25 is not closed, but be opened.Under on the conveying direction A of recess portion 25
Trip side is when being opened, and in the case where generating tilting on medium M, can make the tilting of medium M effectively on conveying direction A
Downstream side loss.Therefore, as shown in Figure 4, even if can inhibit with the tilting if generating tilting on medium M
Caused by fold L growth, it is relatively low so as to which the height of fold L to be suppressed to.This is because, as shown in Figure 3,
By making the downstream side on the conveying direction A of recess portion 25 open, even if to which shape can be passed through if generating tilting on medium M
At the subtle deformed shape T (references generally rhomboidal in shape being continuously formed on conveying direction A and width direction B
Figure 11 and Figure 12), and the tilting is crushed.
Next, to the height of fold L can be suppressed in the case where having used printing equipment 1 of the present embodiment compared with
Low reason illustrates.
Herein, Fig. 5 is to Fig. 8 shows the ejection models of the supporting part 17 of the major part of the printing equipment 1 as the present embodiment
Enclose the summary stereogram around 15.Wherein, it indicates to Fig. 5 medellings producing pleat along the transported medium M of conveying direction A
The state of wrinkle L, indicates to Fig. 6 medellings the state that fold L is grown into caused by medium M, indicates gradual to Fig. 7 medellings
The fold L of growth starts the state being crushed, and indicates that fold L is disperseed by conquassation to Fig. 8 medellings, and be suppressed to relatively low height
The state of degree.
In addition, Fig. 9 to Figure 12 also illustrates that the ejection of the supporting part 17 of the major part of the printing equipment 1 as the present embodiment
Summary stereogram around range 15.Wherein, Fig. 9 schematically indicates that fold L is crushed and is suppressed to the shape of lower height
State.In addition, Figure 10 indicates the conveying with medium M to deformed shape T generally rhomboidal in shape successively to Figure 12 medellings
The state extended along conveying direction A.
For example, when ink is ejected to medium M, medium M can be swollen, to will produce as shown in Figure 5
Fold L (medium M is tilted).Moreover, even if being not in the case that ink is ejected to medium M, there is also because Absorption of Medium it is big
Moisture in gas and the case where generate fold L, or the medium M caused by with being heated to medium M by heater 12
Expansion etc. and the case where generate fold L.
When generating fold L on medium M, fold L may be grown.For example, in state shown in Fig. 5, fold L
In the range of the first bearing surface 3a.However, in state shown in Fig. 6, fold L reaches the second bearing surface 3b.In this way, working as
When fold L growths, the height of fold L also has the trend got higher.
But since the bearing surface of the present embodiment 3 has in the downstream side for depending on conveying direction A compared with the first bearing surface 3a
The second bearing surface 3b with recess portion 25, therefore as shown in Figure 7, becoming can be by the recess portion 25 of the second bearing surface 3b
And the structure for being crushed fold L.
Also, when being formed with the recessed portion D that can be crushed fold L as shown in Figure 7 on medium M, as shown in Figure 8
As, fold L is broken up into fold La and fold Lb, so as to reduce the height of fold L (fold La and fold Lb)
Degree.
Also, further as successively with reference to Fig. 9, Figure 10, Figure 11, Figure 12 it is found that the edges deformed shape T generally rhomboidal in shape
Conveying direction A and extend.In this way, by being formed with multiple changes generally rhomboidal in shape on conveying direction A and width direction B
